Definitions

  • the present invention relates to an information processing device, a press machine system, and a data generation method.
  • a press machine clamps a workpiece between an upper die and a lower die, and performs press processing such as forming on the workpiece.
  • One type of press machine known is a press brake (bending machine) that performs bending processing on plate-shaped workpieces. With this press brake, an operator places the workpiece in a specified position and drives the upper or lower die to clamp the workpiece between the upper and lower dies, thereby performing bending processing. At each stage of bending the workpiece, the operator checks the direction of the workpiece to be pressed against the backgauge using work instructions or design drawings related to the workpiece.
  • the display attributes of the workpiece displayed on the display unit are the same for all processes. For this reason, for example, even if the worker checks the workpiece displayed on the display unit in a certain process, it may be difficult to see and may not be able to check the parts that require attention when placing the workpiece. As a result, depending on the process, the worker may not notice the parts that require attention even when looking at the image displayed on the display unit, and may end up placing the workpiece on the press machine in the wrong orientation. This requires the worker to carefully observe the image displayed on the display unit and find the parts that require attention. However, this work takes time and places a heavy burden on the worker.
  • the object of the present invention is to provide an information processing device, a press machine system, and a data generation method that contribute to reducing the burden on workers.
  • the information processing device is an information processing device that creates a shape model for displaying an image to assist an operator in his work on a display unit of a press machine that processes a workpiece, and includes a data generation unit that generates the shape model when processing the workpiece, an input unit that accepts input of display attributes of the shape model, and a setting unit that sets the display attributes of the shape model when displayed on the display unit to the display attributes accepted by the input unit.
  • a press machine system includes the above-mentioned information processing device and a press machine that processes a workpiece by clamping the workpiece between an upper die and a lower die, and the press machine includes a main body that holds either the upper die or the lower die, a display that is provided on the main body or separately from the main body, and a control device that displays a shape model on the display with the display attributes set in the setting unit.
  • the data generation method is a data generation method for an information processing device that creates a shape model for displaying an image to assist an operator in the work on a display unit of a press machine that processes a workpiece, and includes generating a shape model for use when processing a workpiece, accepting input of display attributes of the shape model, and setting the display attributes of the shape model for use when displaying the shape model on the display unit to the accepted display attributes.
  • the information processing device or data generation method allows the display attributes of the shape model to be set so that it is easy to check the parts that require attention when performing bending. As a result, the worker can passively know the parts that require attention, which contributes to reducing the burden on the worker.

  • the worker can carry out bending work for each process while checking an image corresponding to the process.

  • the setter SL performs a predetermined operation to save the display angle of the shape model MD after the change, that is, the display angle shown in FIG. 10.
  • the predetermined operation is an operation for saving the display angle after the change, for example, an operation of pressing a save button icon displayed on the display device 400.
  • the setting unit 52 stores the display angle of the shape model MD displayed on the display device 400, i.e., the display angle shown in FIG. 10 received by the input unit 42, in the storage unit 21 as a display attribute.
  • the data of the shape model MD of the selected process and the display angle of the shape model MD displayed on the display device 400 are associated with each other and stored in the storage unit 21 as process support data.
  • the parameter set by the setting person SL as the display attribute is not limited to the display angle, and may be the display magnification or the transparency of the work.
  • the setter SL does not have to set the shape models MD for all processes. For example, when the data generation unit 50 creates a shape model MD for each process, the setting unit 52 sets the first display attribute as the display attribute of the shape model MD for each process. In other words, the setting unit 52 sets the first display attribute as the default display attribute of the shape models MD for all processes. Then, when the setter SL wants to change the display attribute of the shape model MD for a specific process among multiple processes, he or she operates the operation unit 44 to change the display attribute of the shape model MD for the specific process from the first display attribute to the second display attribute.
  • the setter SL operates the operation unit 44 to input a second display attribute different from the first display attribute to the information processing device 300. Then, the setter SL performs the above-mentioned predetermined operation to save the setting of the second display attribute.
  • the setting unit 52 changes the display attribute of the shape model MD for the specific process stored in the memory unit 21 from the first display attribute to the second display attribute.
  • the second display attribute may be a display angle at which the part to be noted can be confirmed.
  • the second display attribute may also be the transparency of the shape model MD.
  • the setter SL may increase the transparency of that part to set it to a transparency that allows the part to be noted to be seen through.
  • the setter SL increases the transparency of a part of PK to set it to a transparency that allows the hole HI, which is the part to be noted, to be seen through.
  • the second display attribute may also be the display magnification.
  • the person SL may set the display magnification of the shape model MD in a particular process to be high, with the part requiring attention (e.g., hole HI) as the center position so that the part requiring attention is clearly visible.
  • the display magnification is set as the display attribute, the information on the center position may also be set at the same time.
  • the bending CAM data BD including the process support data for each process stored in the storage device 40, is sent to the press machine 100.
  • the information processing device 300 may transmit the bending CAM data BD to the upper device 200.
  • the setter SL operates the operation unit 44 to cause the information processing device 300 to transmit the bending CAM data BD, including the process support data for each process stored in the storage device 40, to the upper device 200.
  • the upper device 200 receives the bending CAM data BD from the information processing device 300 and transmits the received bending CAM data BD to the control device 4 of the press machine 100.
  • the information processing device 300 may directly transmit the bending CAM data BD to the control device 4 of the press machine 100.
  • the bending CAM data BD is not limited to being transmitted from the information processing device 300 or the upper device 200.
  • the worker OP may connect a storage medium such as a USB memory that stores the bending CAM data BD to the control device 4, and import the bending CAM data BD into the control device 4.
  • the power is turned on to the press machine 100, and the press machine 100 performs start-up operations such as returning to the origin and goes into a ready state (standby state).
  • the worker OP operates the operation unit 24 to input to the control device 4 that the work will begin.
  • the control device 4 detects the input to start the work, it requests the bending CAM data BD from the higher-level device 200.
  • the higher-level device 200 transmits the bending CAM data BD to the control device 4.
  • the control device 4 takes in the bending CAM data BD transmitted from the higher-level device 200 or stored in a storage medium, and stores it in the memory unit 21.
  • the control device 4 controls the projection of an image G for each process onto the projection area PA based on the process support data for each process included in the bending CAM data BD. For example, if the bending work performed by the worker OP has two processes, a first process and a second process, the control device 4 first reads the process support data corresponding to the first process, and projects the shape model MD included in that process support data onto the projection area PA with the display attribute included in the process support data. For example, if a display angle is set as the display attribute, the control device 4 projects an image G including the shape model MD viewed from that display angle onto the projection area PA.
  • the control device 4 projects the image G including the shape model MD of the first step onto the projection area PA at the display magnification set as a display attribute. For example, if the transmittance of a portion of the shape model MD of the first step is set as a display attribute, the control device 4 projects the image G including the shape model MD reflecting that transmittance onto the projection area PA.
  • the control device 4 When the first process is executed, the control device 4 reads the process support data corresponding to the second process, in the same way as the first process, and projects the shape model MD included in the process support data onto the projection area PA with the display attributes included in the process support data. If the bending work further includes a third process and a fourth process, the control device 4 projects an image G corresponding to the process support data for the third process onto the projection area PA, in the same way as the second process, when the second process is executed, and projects an image G corresponding to the process support data for the fourth process onto the projection area PA when the third process is executed.
  • the worker OP bends the workpiece W after checking that the orientation of the workpiece W when it is butted against the backgauge 7a is the preset orientation.
  • the worker OP may mistake the orientation of the workpiece W, resulting in a processing defect in which the workpiece W is bent to the opposite side. Therefore, in order to prevent the worker OP from making a mistake in the orientation of the workpiece W, the press machine 100 displays an image showing the orientation of the workpiece W when it is butted against the backgauge 7a on the display unit of the press machine 100 for each process.
  • the display attribute of the model representing the workpiece W is set to one value in all processes, regardless of the process.
  • the display angle of the shape model representing the workpiece W is set to only a certain display angle, regardless of the process. Therefore, even if the above image is displayed on the display unit of the press machine 100, if the image is the image shown in FIG. 11, the worker OP cannot check the hole HI, which is the part requiring attention.
  • the information processing device 300 of this embodiment has a configuration in which the display attributes of the shape model MD when the shape model MD is displayed on the display unit of the press machine 100 are set to the display attributes received by the input unit 42. This makes it possible to set the display attributes such as the display angle of the shape model MD so that the parts that require attention when performing bending can be easily confirmed. Therefore, it is possible to display the image G illustrated in FIG. 14 on the display unit of the press machine 100 instead of FIG. 11.
  • the worker OP can passively know the above-mentioned parts that require attention (for example, hole HI) by checking the image G shown in FIG. 14 when performing bending work.
  • the work of the worker OP to find the parts that require attention while operating the operation unit 24 can be eliminated or reduced, and the burden on the worker OP can be reduced.
